SEL-FT50/SEL-FR12 Fault Transmitter and Receiver System Instruction Manual Date Code 20170317

Appendix B: Two Branch Application

With these settings, Branch B operates using a fuse-blowing scheme where the

fuse clears faults on the branch, while Branch A operates separately, tripping

much faster because the protection does not wait for a fuse-coordination delay.
